Cressida Bonas

We're just months away from the wedding of Prince Harry and Meghan Markle, and the royal couple is no doubt dealing with all the little hiccups and headaches that comes with planning such a massive ceremony.

There's the guest list, the menu, the bridesmaid dresses, and of course, the thirsty-ass exes trying to steal the bride's shine.

Kate Middleton and Cressida Bonas might both be royals pretty soon as Prince Harry will likely propose to Bonas in 2014, but an upcoming book implies that neither of them should really be members of the House of Windsor at all.

Marcia Moody, in her book Harry: A Biography, says "Kate and Cressida aren't a natural fit, left to their own devices."
